Artic dump trucks have a history that traces back to, of all things, a tandem ag tractor conceived in the 1950s in England by an Essex farmer.
Early History
Ernest Doe bought two Fordson tractors, removed the front axles from each tractor and connected the front end of one to the rear of the other using a hydraulic turntable. Voila! A tractor with doubled power. The cantilevered front engine rode on air and the whole tandem machine rode on four treaded rear tires powered by the twin engines. It was called a Doe Triple D (Doe Dual Drive) tractor.
